1kestose
1kestose is a trisaccharide, meaning it is composed of three monosaccharide units. Specifically, it is an isomer of kestose, and it is characterized by a unique linkage between its constituent sugars. The exact structure of 1kestose involves a fructose molecule linked to a glucose molecule via an alpha-1,2 glycosidic bond, and this disaccharide unit is then linked to another glucose molecule through an alpha-1,6 glycosidic bond. This specific arrangement distinguishes it from other kestose isomers. 1kestose is a type of fructan and is classified as a soluble dietary fiber. It is found naturally in various plants, particularly in onions, garlic, asparagus, and chicory. Like other fructans, 1kestose is not digestible by human enzymes in the small intestine. Instead, it passes to the large intestine where it can be fermented by beneficial gut bacteria. This fermentation process can produce short-chain fatty acids (SCFAs), such as butyrate, acetate, and propionate, which are considered to have positive effects on gut health. Due to its prebiotic properties, 1kestose is sometimes added to functional foods and dietary supplements. Its presence in the diet can contribute to a healthier gut microbiome and may have implications for digestive well-being.
